The official statistics show that 60 per_cent are employed workers or independent professional people .

(James A. Ibers et al., "Proton magnetic resonance...)

A number of semiempirical estimates by various workers lead to the conclusion that the **f bond becomes symmetric when the **f bond length is about 2.4 to 2.5 A , but aside from the possible example of nickel dimethylglyoxime there have been no convincing reports of symmetric **f bonds .

(J. F. Vedder, "Micrometeorites", in Francis S. J...)

Many workers believe that the response is proportional to the incident momentum of the particles , a relation deduced from laboratory results linearly extrapolated to meteoritic velocities .

And there are now many millions of workers for whom the factory with the big parking_lot , which can be reached by driving across or against the usual pattern of rush_hour traffic and grille route bus_lines , is actually more convenient than the walk-to factory .
